Hi @Cruiser
My suggestions for when you get home would be to make sure you have a lightweight towel! I found my normal towel just too bulky and heavy, also if possible put your microwave at waist height (if it isn't already). I did what you have done and prepared loads of frozen meals to make life easier, it helped so much.
I must say, I completely understand how hesitant you are about losing your independence, I am the same and if I lived alone I would not want anyone staying or 'looking after' me either.
I found that post op I did not have a lot of pain and my drain (for wide local excision) was removed before I left hospital.
Wishing you all the best.
